IMPROVEMENT IN AWNINGS.

Specification forming part of Letters Patent No. 137,772, dated April l5, 1873;A application tiled September. '7, 1872.

To all whom it may concem:

Be it knownthat I, GEORGE W. GERAU, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Ventilating Wing-Awning, of which the following is a specification: v

In the accompanying drawing, Figure l is a front elevation of my invention. Fig. 2 is a vertical centralsection, and Fig. 3 a horizontal section, of the same.

Similar letters df reference indicate corresponding parts.

The invention consists of certain improvements in awnings, which will rst be fully described and then clearly pointed out in the claim.

A in the drawing is the lower U-frame, by which the awning B is held extended in front of the wall or window-frame C. This frame A is hinged and made up and down adjustable in the ordinary or suitable manner. The front a of the awning is securely connected with the front of the U-fralne. Its side wings b b are, however, not so secured, but are provided with hooks or other devices d d, whereby they can be fastened to the face of the wall. When the air is to be admitted at one side of the awning the wing b at that side is unfastened from the wall and swung out, as in Fig. 3, and held out by a rigid brace or bar, D. The inner end of this brace is iitted into a ring or socket, e, that is provided for its reception on the window sill or frame. The outer end -hooks into a loop on the wing b. In this manner the Wing is held open and air freely admitted to one side of the awning. When the sun does not strike either side ofthe awning both wings may be thus opened and a 'regular draft created in front of the window. At night especially such thorough ventilation wiil be desirable. To facilitate the opening of these wings their lower parts are detached from the front a, as shown at f in Fig. l. E E are two inner wings or flaps arranged within the awning near to the wings b b, respectively. They are sewed fast at the junction of the wings b and front a. When one wing b is swung open, as in Fig. 3, the wing E pertaining to it is stretched across the awning diagonally and fastened to the windowframe by hooks or otherwise, making thus a continuation of the open wing b and a clear passage for the entrance of air into the room.

In place of two inner wings, E, but one may be used, fastened to the inner side of a, equi- A distant from the wings b.

The same principle of invention can be applied to old awnings by merely taking the frame out at the sides.

Having thus described my invention,I claim as new and desire to secure by Letters Patent- 1. The brace D, combined with the sideV wing b of an awning, substantially as set forth.

2. The awning provided with the inner wing or wings E and with the opening side wings b b, substantially as herein shown and described.
